Benefits of technology

[0009]The present invention solves the existing need by providing a battery cable with provisions for integral circuit protection, which has structural and performance characteristics as to adequately guard from voltage fluctuations in the battery supply.
[0010]According to one preferred embodiment of the present invention, a battery cable circuit protection device for preventing fluctuations in voltage from a supply battery is provided. The device includes a terminal base having a battery cable lug member adapted for mounting to and making an electrical connection with a battery post of the battery. A battery cable mounting structure is fixedly connected to the terminal base for detachably connecting the terminal base to a battery cable. The battery cable supplies a vehicle starter motor with electrical energy. A first fuse mount supported by the terminal base provides electrical interconnection to the battery post. A second fuse mount supported by the terminal base provides electrical energy to vehicle electrical systems other than the vehicle starter motor. The first and second fuse mounts are adapted for detachable connection to a fuse which provides electrical interconnection between the first and second fuse mounts.
[0011]According to another embodiment of the present intention, a circuit for preventing fluctuations in voltage from a supply battery comprising the battery cable circuit protection device of the present invention is provided.

Problems solved by technology

The integrated circuits for the various electric loads may suffer damage where overvoltages or undervoltages appear at the power supply.
Consequently, the manufacture of these circuit types (e.g., components and processing) is expensive.
Such system, however, also aggravates the manufacturing costs as well as add to the cost of assembling the electric system to a vehicle (e.g., costs of additional parts).

Embodiment Construction

[0019]FIGS. 1A and 1B are plan views of a battery cable circuit protection device according to an exemplary embodiment of the present invention. Referring to FIGS. 1A and 1B, the battery cable circuit protection device 10 comprises a terminal base 12, a high-current main fuse 14, and a fuse cover 16. The battery cable circuit protection device 10 of the exemplary embodiment adequately protects the battery supply from voltage fluctuations (e.g., overvoltages or undervoltages).

[0020]The terminal base 12 has a battery cable lug or post 102 preferably adapted for mounting to a studded battery post 100a of a battery 100, as illustrated in FIG. 1C. FIG. 1C shows the battery cable circuit protection device 10 being mounted on the battery 100. It will be appreciated by those skilled in the art that the battery cable post 102 can also be mounted to other battery terminals, such as a SAE taper post battery terminal, etc. The battery post 100a is secured to the battery cable post 102 via a nut...

Abstract

A battery cable circuits protection device (10) and circuit for preventing fluctuations in voltage from a supply battery (100) is provided. The device includes a terminal base (12) having a battery cable lug member (102) adapted for mounting to and making an electrical connection with a battery post (100a) of the battery. A battery cable mounting structure (12a, 12b) is fixedly connected to the terminal base for detachably connecting the terminal base to a battery cable. The battery cable supplies a vehicle starter motor with electrical energy. A first fine mount (14a) supported by the terminal base provides electrical interconnection to the battery post. A second fuse mount (14a) supported by the terminal base provides electrical energy to vehicle electrical systems other than the vehicle starter motor. The first and second fuse mounts are adapted for detachable a connection to a fuse (14), which provides electrical interconnection between the first and second mounts.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a battery cable circuit protection device and, more particularly, to a battery cable with provisions for integral circuit protection.[0003]2. Description of the Background Art[0004]Generally, a battery is mounted inside a vehicle as a power source of electrical power, and electronic, integrated circuits are designed to drive on voltage from the battery and through the vehicle's electric system. As used in this application, the term “vehicle” refers to any motor vehicle including, but not limited to, a car, truck, van, tractor trailer, bus, etc.[0005]Electric system distribution lines may be affected by sharp voltage fluctuations due to sharp changes in the input current to components of the vehicle (e.g., air conditioner, lights, windshield wipers, etc.). The integrated circuits for the various electric loads may suffer damage where overvoltages or undervoltages appear at the p...
